Patent TW-394800-B (TW)
Title: Surface modification and/or fabrication techniques
Inventor: MISTRY PRAVIN
IPC: C23C14/22
Filed: 1995-07-17
Granted: 2000-06-21
Abstract: Laser energy is directed at a substrate to mobilize, vaporize and react a constituent (primary) element (e.g., carbon) contained within the substrate, so as to modify the composition (e.g., crystalline structure) of the constituent element, and to diffuse the modified constituent back into the substrate, as an adjunct to fabricating a coating (e.g., diamond or diamond-like carbon) on the surface of the substrate.  This creats a conversion zone immediately beneath the substrate, which transitions metallurgically from the ocmposition of the underlying substrate to a composition of the coating being fabricated on the surface of the substrate, which results in diffusion bonding of the coating to the substrate. Additional (secondary) similar (e.g., carbon) or dissimilar elements may be introduced in a reaction zone on and above the surface of the substrate to augment the fabrication of and to determine the composition of the coating.  The laser energy is provided by a combination of an excimer laser, an Nd:YAG laser and a CO2 laser, the output beams of which are preferably directed through a nozzle delivering the secondary element to the reaction zone. The reaction zone is shielded by an inert (non-reactive) shielding gas (e,g,, N2) delivered through the nozzle. A flat plasma is created by the lasers, constituent element and secondary element on the surface of the substrate and the flat plasma optionally extends around the edges of the substrate to fabricate a ocating thereon.  Pretreatment and coating fabrication can be performed in conjunction with one another (in-situ). Alternatively, a substrate can be pre-treated to characterize its surface for subsequent coating. In either case, certain advantageous metallurgical changes are included in the substrate due to the pre-treatment. The processes (pre-treatment and coating fabrication) are suitably performed in ambient, without preheating the substrate and without a vacuum. Substrates of numerous geometries, sizes and shapes, such as flat cutting tool inserts as well as round cutting tools, are readily coated in this manner. The lasers are directed at any suitable angle (including coaxial) relative to the substrate and or the plasma.
Patent TW-385349-B (TW)
Title: Method and apparatus for screening a fiber suspension
Inventor: AALTONEN FRANK
IPC: B01D29/35
Filed: 1995-08-14
Granted: 2000-03-21
Abstract: The differences in performance of a screening cylinder during screening of a fiber suspension (e.g. low consistency paper pulp) at the inlet end compared to the reject end is accommodated by constructing the feed side surface of the screening cylinder so that it induces greater turbulence in the vicinity of the screen cylinder surface adjacent the reject end of the screen than adjacent the inlet end. Typically this increase in turbulence is at least about 10% (preferably at least about 40%, and typically greater than 100%). The turbulence increase can be provided by a substantially smooth screening medium surface at the inlet end and a contoured screening medium surface adjacent the reject end, or by first and second contoured surfaces of different aggressiveness. Contoured surfaces typically include grooves, and variables that may be changed to affect the turbulence include the depth of the grooves, the angle of inclination of the downstream wall of the grooves, the radius of curvature of the opening (holes or slots) edges, the frequency of openings in grooves, and the dimensions of the openings (holes or slots) in the grooves. The screen cylinder is mounted in a pressure screen housing.

Title: Self molding insole insert
Inventor: JOHN A HOFFMANN III
IPC: A43B7/28
Filed: 1995-11-14
Granted: 1996-10-01
Abstract: An insert for a shoe comprises a pouch having a moldable, thixotropic material and a shell having a catalyst. The shell is capable of being ruptured by massaging the pouch to allow the catalyst to be released from the shell and mixed with the material. A pressure sensitive adhesive is on the bottom of the pouch to secure it to the inner sole of a shoe, and a nylon layer is on the top of the pouch to absorb moisture and provide an aesthetic appearance. In use, the pouch is massaged to mix the catalyst and moldable material and is then placed in a shoe. The user places a foot in the shoe and applies a light weight to thefoot so that the pouch assumes the shape of the foot bottom and fills that space between the foot and the shoe. Then, the foot is removed to allow the material to cure. When the material is cured the insert prevents excessive collapse of the foot.

Filed: 1997-03-10
Granted: 2001-01-01
Abstract: In a margin exposure apparatus for projecting exposure light to a marginal portion of a resist coated substrate while rotating the same, any displacement of the substrate in a direction of exposure light projection is detected and, on the basis of it, the state of focus of the exposure light upon the substrate is corrected. This effectively prevents degradation of margin detection precision or exposure precision due to variation in height of the marginal portion of the substrate resulting from warp or vibratory rotation of the substrate.

Title: Character image processing apparatus and method
Inventor: SATO YUKIMASA
IPC: G06F3/12
Filed: 1997-12-17
Granted: 2000-08-11
Abstract: A character image processing apparatus so adapted that when a typeface and size are specified at generation of a character image, a font of a specified typeface and of a size within predetermined selection limits of a specified size is retrieved from pre-rasterized fonts already developed as bitmap data and stored. In a case where a character image is generated from this font, the character will be generated at a position offset from the position the character of the specified size would have originally occupied. Accordingly, position is corrected in such a manner that the center of the position which  a character would have originally occupied and the position of the center of the character generated from the pre-rasterized font will coincide. Further, the selection limits are decided using sizes midway between a stored pre-rasterized font and character sizes one size larger and one size smaller than that of this pre-rasterized font as boundaries.

Title: Apparatus for simulating a biological neuron
Inventor: GORELIK VLADIMIR A
IPC: H01L29/68
Filed: 1998-03-16
Granted: 1999-11-01
Abstract: An apparatus for simulating the behavior of a biological neuron. In accordance with one aspect of the invention, a charge-carrying component is fabricated from semiconductor material and is disposed above a semiconductor substrate. The charge-carrying component is separated from the substrate, and substantially surrounded, by an isolating material, such as an oxide (e.g. silicon dioxide). Advantageously, the substantial isolation of the component helps ensure the preservation of electrical charge on the charge-carrying component. Indeed, in accordance with a preferred embodiment, virtually no charge leakage occurs, and absent purposeful charge injection or drainage (described below), the charge deposited on the charge carrying component will be preserved for a very long time. In order to control the quantity of charge carried on the charge-carrying component, a charge injector is disposed adjacent to the charge-carrying component, a charge injector is disposed adjacent to the charge-carrying component and is configured to controllably transfer charge to the charge-carrying component. Similarly, a drain disposed adjacent to the charge-carrying component and configured to controllably transfer charge away from the charge-carrying component. The charge injector and drain of the preferred embodiment of the present invention are structurally similar to charge injectors and drains conventionally used in EEPROM technology. To generate an output, a charge sensor disposed in proximity with a charge sensing location on the charge-carrying component, and an output is provided and disposed in communication with the charge sensor. As a result, the output delivers an electrical signal that is indicative of the charge sensed by the charge sensor.
